Answer:
Step-by-step explanation:
( (625)^(1/2) )^1/2
The safest and best way to do this is one set of brackets at a time using 1 exponent at a time.
The next best way is to combine the exponents and find the 1/4 root once. Both answers should be the same.
(625)^1/2 = sqrt(625) = 25
(25)^1/2 = 5
((625)^(1/2))^1/2 = 625^1/4 = 5
